Denitrification is a process by which bacteria reduce nitrate (NO3-) to nitrogen gas (N2) in anaerobic conditions. This process involves a series of reduction steps, with nitrate being converted to nitrite (NO2-), then to nitric oxide (NO), then to nitrous oxide (N2O), and finally to nitrogen gas (N2). Therefore, the correct answer is B, as denitrification is a process of reducing nitrate.
